See, speak, and instant message other people on Skype. Skype is free, and all you need for video or voice calls is a webcam and/or microphone.

Using Skype, you are not limited to communicating with just one person at a time, because Skype also allows group conversations, and the latest version is now offering group video chatting.

Skype also features landline and mobile calls and messaging, but to use these features requires that you spend money. Skype to Skype calls are totally free and unlimited, so don't think that you have to pay to use Skype.
